Last updated: October 7, 2026 · By Juan Valenzuela, Certified Children’s Shoe Fitter

Most parents put a lot of thought into hiking boots, but socks matter just as much. The right pair protects your child’s feet from rubbing, keeps them dry, and cushions every step over rocks and roots. As a certified children’s shoe fitter, I look for kids’ hiking socks that are breathable, cushioned where the foot takes the most impact, and tall enough to protect the skin from the boot. Here’s what to look for, and my top picks.

What to Look for in Kids’ Hiking Socks

Extra Cushioning Where It Counts

The best hiking socks have extra padding at the heel and the ball of the foot, which take the most impact on the trail. The cushioning absorbs shock and reduces rubbing, which helps prevent blisters.

Breathable, Moisture-Wicking Fabric

Kids’ feet sweat a lot, and damp feet blister quickly. Breathable socks that pull moisture away from the skin keep feet cooler, drier, and more comfortable on long hikes.

The Right Material: Wool, Not Cotton

Wool is the material I recommend most. It wicks moisture, stays warm even when damp, and is naturally odor-resistant. Merino wool is especially soft, so it doesn’t itch the way some kids expect wool to.

Avoid all-cotton socks for hiking. Cotton holds onto sweat, and wet socks are one of the main causes of blisters on the trail.

How Tall Should Hiking Socks Be?

Hiking socks come in many heights, from ankle socks to knee-highs. Choose a sock that comes up at least as high as the top of your child’s boots, so the boot cuff never rubs against bare skin.

How to Get the Right Sock Size

Socks that are too small squeeze the toes and make them rub against each other. Socks that are too big bunch up under the foot, and that extra material causes blisters.

Instead of going by age or the sock size, check the shoe size printed on the label. It gives a more accurate fit.

How to Check the Fit

Once your child puts the socks on, make sure the heel of the sock lines up with the back of their heel. If the heel sits on top of the foot or under the arch, the sock is the wrong size and will bunch up inside the boot.

Pair Them with the Right Hiking Boots

Even the best socks can’t fix boots that don’t fit. Look for hiking boots that are lightweight, supportive around the ankle, and waterproof for wet or muddy trails. See my picks for hiking boots for kids with wide feet and hiking boots for kids with narrow feet.

FAQ

Are wool socks itchy for kids?

Merino wool is much softer than regular wool, and most kids find it comfortable. Wool blends with nylon or spandex are softer still.

Can kids wear cotton socks for hiking?

I don’t recommend it. Cotton holds sweat, and wet socks are one of the main causes of blisters on the trail.

How tall should kids’ hiking socks be?

At least as tall as the top of the boot, so the boot doesn’t rub against bare skin.
